U.S.- Germany Cooperative Research: Process Chains for the Replication of Complex Optical Components: High Resolution Surface Zone Analysis

该奖项支持唐·卢卡和俄克拉荷马州立大学的学生与德国亚琛大学和不来梅大学广泛合作。该项目将专注于发现是什么因素引发了新一轮高科技浪潮。由此产生的美德跨地区合作研究中心涉及16个技术项目，重点是为下一代信息技术和电信、医疗保健、生命科学、传感、照明和能源转换应用开发制造复杂、高质量光学元件的工艺。在设计、HAD涂层、复制技术和测量科学技术领域有技术项目。除了这里描述的项目外，这个长期研究中心的资金主要由德国国家科学基金的对应机构德国联邦研究基金会提供。美国项目“高分辨率表面区分析”的研究重点是研究溶胶-凝胶衍生的金刚石可旋转硬模涂层的近表面机械性质，这些涂层将用于聚合物和玻璃的超精密光学元件的批量生产。利用纳米压痕技术研究硬质涂层的近表面力学性能，包括弹性模数和硬度，以及表面残余应力状态。将使用一种新开发的近表面区域分析方法，对横截面和锥形截面涂层进行深度剖析研究。利用纳米划痕技术研究模具涂层的附着力和剥离行为。该项目还将进一步促进开发在纳米尺度上评估近地表机械状态所需的先进表面表征工具。

0128050LuccaThis award supports Don Lucca and students from the Oklahoma State University in an extensive collaboration with the universities of Aachen and Bremen in Germany. The project will focus on discovering what factors are generating the new wave of high-tech The resulting U.S.-Germany Transregional Collaborative Research Center involves sixteen technical projects centered on the development of processes for the manufacture of complex, high-quality optical components for next generation applications in information technology and telecommunications, health care, the life sciences, sensing, lighting, and energy conversion. There are technical projects in the areas of deign, had coatings, replication techniques, and measurement science and technology. Funding for this long-term research center, with the exception of the project here described, is being supplied mainly by the Deutsche Forschungsgemeinschaft, the German counterpart to NSF. The research focus of the U.S. project, "High Resolution Surface Zone Analysis," is the investigation of the near-surface mechanical nature of sol-gel derived diamond-turnable, hard mold coatings which will be used in the volume production of ultraprecision optics of polymers and glasses. Nanoindentation will e used to study the near-surface mechanical properties including elastic modulus and hardness, and the surface residual stress state of the hard coatings. Depth profiling studies will e performed on cross-sectioned and taper-sectioned coatings with a newly developed method for near surface zone analysis. The adhesion and delamination behavior of the mold coatings will be explored with the use of nanoscratching. The project will also further contribute to the development of advanced surface characterization tools needed for assessing the near-surface mechanical state at the nanometer scale.
